Safety

Landslide Kills 35 at Railway Tunnel Entrance in China 27.12.2007

A landslide occurred at around 8:40 a.m. on 20th November, 2007 near the entrance to a railway tunnel and a tributary of the Three Gorges Dam reservoir, in central China's Hubei province. Nearly 4,000 cubic metres of rock plunged onto a highway in Badong county, killing a construction worker busy on the tunnel above the landslide and burying two of his co-workers. Workers had been reinforcing the ceiling of the Yichang-Wanzhou railway tunnel when the landslide happened. The landslide occurred at the entrance of the tunnel further up the hill in Badong, Enshi prefecture. The stone suddenly became loose and soft and then collapsed.

A long-distance bus that just happened to pass that spot at the time of the landslide was buried under giant boulders. It was discovered under rubble on the road three days later. Thirty-two passengers were aboard the vehicle. They all died. Rescuers reached the front of the bus at around 4:00 a.m. on 23rd November but found no signs of life, said sources from China Railway Tunnel Group, the contractor.

The landslide left about 1,000 cubic metres of rubble on National Highway 318, which connects Shanghai and Tibet and is the main route for all motor vehicles in western Hubei. The highway lies 28 metres down the hill from the railway tunnel entrance. More than 740 rescuers worked at the site, clearing up 3,850 cubic metres of debris and 514 tonnes of steel and iron framework.

The accident occurred amid growing criticism of the environmental degradation (erosion, landslides and earth tremors) caused by the dam, a massive engineering project completed in May 2006. As critics predicted, higher water levels appear to have increased the pressure at the base of the cliffs, causing already unstable ground to give way around the reservoir. Since September, a growing number of engineers, dam officials and environmentalists have been predicting a catastrophe unless the central government spends the money to correct erosion and instability caused by the project.

Government officials have insisted that the damage can be controlled and that the benefits of hydropower and flood control far outweigh any environmental damage and the relocation of an estimated 1.2 million people for the project. The site of the accident is about four hours' drive to the dam, the world's largest hydropower project, but there is no evidence at present to suggest that the landslide had been caused by work at the dam or its reservoir, they said.

China Railway Tunnel Group said the landslide might be related to changes in the climate. Four days of rain may have loosened the rock and earth, they said. 52/07-01/08.
